Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Peppermint leaf (Mentha × piperita) has a long history of traditional use for relieving respiratory congestion. Historical records show that peppermint tea and inhalations have been used in various cultures to help clear the lungs and ease breathing difficulties. The key constituent in peppermint, menthol, is known for its cooling and soothing sensation, which can subjectively make breathing feel easier. Menthol is commonly included in over-the-counter cough and cold remedies, and inhaling menthol vapor can provide a sense of improved airflow in the nasal passages.

However, scientific evidence specifically supporting peppermint leaf (as opposed to isolated menthol or peppermint oil) for lung congestion is limited. Some studies suggest that menthol may trigger cold receptors in the nose and airways, leading to a subjective feeling of improved airflow, but objective measures of lung function improvement are lacking. Most clinical research focuses on menthol rather than whole peppermint leaf preparations.

In summary, the use of peppermint leaf for lung congestion is primarily supported by traditional practices rather than robust scientific evidence. The evidence rating is moderate (2 out of 5) due to the consistency of traditional use and plausible mechanisms related to menthol, but the lack of direct clinical studies using peppermint leaf itself limits stronger recommendations.
